Your starting prompt.
Calculate the sample and approximate duration needed for a conversion experiment using our observed baseline, [minimum useful effect], chosen significance level, statistical power and assignment ratio. State the statistical method and distinguish percentage-point changes from relative changes. Compare several plausible baseline rates and account for unavailable traffic. Save the calculation and sensitivity table. Flag when the proposed timeline cannot support the intended decision.

Method and review
Keep the assumptions visible.
State the hypothesis, baseline, unit economics and decision rule. Compare total contribution and uncertainty, and separate modeled scenarios from measured experimental results.
For this task, check
The calculation assumes an appropriate independent-observation model; cluster assignment or repeated measures needs a different variance treatment.
This starting prompt has no published worked example yet. Begin with a small sample and check the calculations before relying on the result.
